2 Claims. (Cl. 124-22) My invention relates to sporting equipment, andmore particularly to an improved arrow projecting gun.

An object of my invention is to provide an improved arrow projecting gunhaving an elastic tubular-shaped sling member.

Another object of my invention is to provide an improved arrowprojecting gun wherein the ends of the sling are frictionally secured toa support at the forward end of the gun.

Yet another object of my invention is to provide an arrow projecting gunhaving means to prevent the closed or loop end of the sling from risingabove the end of an arrow when firing.

Still another object of my invention is to provide an improved arrowprojecting gun having means to retain an arrow in seated firing positionon the gun barrel.

With these and other objects in view, which may be incident to myimprovements, the invention consists in the parts and combinations to behereinafter set forth and claimed, with the understanding that theseveral necessary elements, comprising my invention, may be varied inconstruction, proportions and arrangement, without departing from thespirit and scope of the appended claims.

In order to make my invention more clearly understood, I have shown inthe accompanying drawings means for carrying the same into practicaleffect, without limiting the improvements in their useful applicationsto the particular constructions, which for the purpose of explanation,have been made the subject of illustration.

In the drawings:

Figure 1 is a top plan view of the gun of the present invention showingan arrow in the firing position;

Fig. 2 is a side elevational View of the gun shown in Fig. 1;

Fig. 3 is an enlarged top plan view showing the means used to retain thearrow on the gun barrel;

Fig. 4 is a sectional vieW along line 4--4 of Fig. 3;

Fig. 5 is an enlarged top plan view of the portion of the gun shown inFig. 3, with the guard plate removed;

Fig. 6 is a top plan view of the cross member at the forward end of thegun; and

Fig. 7 is a front view of the cross member.

Referring to the drawings, and more particularly to Figs. 1 and 2, thearrow projecting gun comprises a stock 1, and a fore stock portion 2,having a barrel member 3 formed integral therewith, the front end of thebarrel having a rigid cross-member 4 secured thereto. As will be seen inFigs. 6 and 7, the cross-member 4 is provided with slots 5 adapted toreceive the ends 6 of a piece of rubber tubing 7, forming the slingmember, the ends of the tubing being frictionally held in seatedposition in the slot by means of suitable wedge members 8 fitted intothe ends of the tubing. It will be noted that the sides of the slots aretapered inwardly, as viewed from the front of the cross-member (Fig. 6),and accordingly, when the tubing is stretched to cocking position themembers 8, which are formed with a taper complementary to the sides ofthe slots, securely wedge the ends of the tubing in seated position inthe slots. The closed end, or loop portion 9 of the tubing 7, isreinforced, as by Winding with cords or other suitable material, toprovide an arrowengaging portion of smaller diameter than the remainderof the tube.

The barrel 3 of the gun is formed with a groove 10, adapted to receivean arrow 11, the bottom of the groove having a contiguous slot 12,designed to accommodate one of the feather guides 12 at the rear of thearrow, when the arrow rests in the grooved portion 10. The rear of thebarrel (Fig. 5), is rounded as shown, and forms the front wall of acut-out portion in the upper surface of the fore stock, the rounded Wallhaving a metal strip 13 secured thereto so as to present a smoothsurface of contact for the loop of the sling. The fore stock is suitablyrecessed in portion 14 thereof to provide a guide for a trigger member15. As will be seen in Fig. 4, the trigger 15 is pivotally mounted onthe stock by means of a pin 17, and is connected to a plunger 16 by apin 18, the trigger being biased to its normal non-firing position by aspring 19, which surrounds the plunger.

In order to maintain the arrow in seated position in groove 10 of thegun barrel, there is provided a guard member, designated generally bynumeral 20, comprising a plate 21, having an offset 22, and terminatingin a reduced end 23, the offset portion of the plate and its integralreduced end 23 being spaced in overhanging relation with respect to thegrooved -fore stock. Att-ached to the plate 21 and projecting throughthe slotted portion 20 of the offset is a spring member 24, the free end25 thereof being biased downwardly in the direction of the barrel grooveso as to engage with the end of the arrow when the arrow is in firingposition on the gun barrel. It will thus be seen, that when the arrow isin ring position, the end portion beyond the feathered guides seatsunder the linger of spring member 24, and is securely clamped betweenthe finger and the barrel. It will also be noted that the reduced end 23of plate 21 overhangs the slotted portion of the upper surface of thefore stock, and overhangs the arrow, thus perventing the loop fromrising above the end of the arrow, when the gun is tired.

Sighting means comprising a sight rod 26 may be provided. In thearrangement shown, the fore stock is bored a suicient depth to receivethe rod, which is notched at 27, and held in adjusted position by meansof a detent or plunger 28, biased to seated position by a spring 28'.

In use, the gun is cocked by stretching the tubing until the loopportion 9 can be seated in the cut-out formed in the top portion of thefore stock. When so seated, the inner surface of the loop is in contactwith the metal strip 13 attached to the rounded front wall of thecut-out. The arrow is then placed in the grooved portion 10 of thebarrel, with one of the feathered guides projecting into the slot 12,and then moved rearwardly of the barrel until the end beyond the guidesfits under finger member 25. When it is desired to project the arrow,trigger 15 is pulled in a direction to move plunger 16 upwardly and liftthe loop out of the recess and in contact with the end of the arrow andproject the same.

While I have shown and described the preferred embodiment of myinvention, I wish it to be understood that I do not confine myself tothe precise details of construction herein set forth by way ofillustration, as it is apparent that many changes and variations may bemade therein, by those skilled in the art, without departing from thespirit of the invention or exceeding the scope of the appended claims.
